CDM-VW300 Series Dynamic Vibrating-Wire Analyzers
difficult to resolve. Data-acquisition systems, from the sensors to the 
telecommunications equipment, are complex. Campbell Scientific equipment 
and software are among the best available, but the integration process can be 
demanding and involves trial and error; contingencies should be developed to 
address possible problems. Do the bulk of the integration work in a 
comfortable and dry location that has a communications link with Campbell 
Scientific during regular business hours. If you are experienced with field 
deployments, set aside at least a full day for pre-configuration work. 
Otherwise, set aside three to seven days for system development before 
travelling to the field. 
6.1 Laboratory-Mode Installation
IMPORTANT — Do not connect the CDM-VW300 analyzer or SC-CPI 
interface to a PC until AFTER installing DVWTool 1.0 or later or DevConfig 
2.04 or later. Consult Section 7.1.1, Software and Driver Installation, for more 
information. 
Laboratory mode allows for easy examination and validation of measurements. 
To ensure a successful field deployment, perform this procedure before 
stepping through the field-mode installation procedure of Section 6.2, Field-
Mode Installation. 
As illustrated in the following figure, a connection is made directly between 
the CDM-VW300 and a PC via USB cable. No datalogger is required. 
DVWTool support software is used to configure, communicate with, and obtain 
sensor readings from the CDM-VW300.
